Doctors removed a billion of his T-cells — a type of white blood cell that fights viruses and tumors — and re-engineered them to attack his cancer. Then the altered cells were dripped back into Mr. Ludwig’s veins.

At first, his vital signs took a nose-dive and doctors thought he might die.

But, a few weeks later, “the fevers were gone. And so was the leukemia.”
